This you can see from what has already been said; but I need to add that an earthly-minded person is a complete person when the spiritual level has been opened within. Once that happens, we are actually in the company of angels in heaven at the same time that we are in the company of people on earth, living under the watchful care of the Lord in both realms. Spiritual-minded people derive their imperatives from the Lord through the Word and carry them out by means of their earthly selves.
Earthly-minded individuals whose spiritual level has been opened do not realize that they are thinking and acting from their spiritual selves. They seem to themselves to be acting on their own, though in fact it is not on their own but from the Lord. Earthly-minded people whose spiritual level has been opened do not realize that they are in heaven because of their spiritual selves, either, even though their spiritual selves are surrounded by heaven’s angels. Sometimes such people are even visible to angels, but since they are drawn back to their earthly selves, they vanish in a little while.
Earthly people whose spiritual level has been opened do not realize that their spiritual minds are filled with thousands of hidden treasures of wisdom and with thousands of love’s joys as gifts from the Lord. They do not realize that they will begin to participate in this wisdom and joy after they die, when they become angels. The reason earthly-minded people are not aware of all this is that communication between our earthly and our spiritual selves takes place by correspondences, and communication by correspondences is perceived in our understanding only as seeing truths in the light, and in our will only as being helpful because we enjoy it.
